Can laryngeal cancer be cured after minimally invasive surgery

Can laryngeal cancer be cured after minimally invasive surgery? The occurrence of laryngeal cancer has a great impact on people's production and life, so people are more concerned about the treatment effect of the disease. They hope that patients can fully master some scientific and cultural knowledge so that they can be invincible in the process of dealing with the disease. Therefore, these are of great benefit to people.

Generally, the cure rate of early laryngeal cancer can reach 90%. For radical laryngeal cancer, if local recurrence occurs, total laryngectomy can still achieve a cure rate of 68%. However, for patients who relapse after radical surgery, the curative effect of radiotherapy is very poor, with a cure rate of no more than 10%.

The cure rate of surgery and radiotherapy for stage I laryngeal cancer is over 90%. Stage II and some stage III tumors can be treated with laryngeal function-preserving surgery, sometimes including neck dissection. For stage I or II voice reconstruction surgery, some patients can gain language communication ability. After surgery, voice function can be restored through esophageal voice, artificial voice generator, etc. Advanced laryngeal cancer should be treated with total laryngectomy, sometimes including neck dissection.

Currently, the treatment of laryngeal cancer includes surgery, radiotherapy, chemotherapy and biological therapy, etc. Sometimes multiple treatment methods are combined to improve the 5-year survival rate of laryngeal cancer, maximize the retention of the patient's laryngeal vocal function, and improve the patient's quality of life.

Surgery

In histology and embryology, the left and right sides of the larynx develop independently, and the supraglottis, glottis and subglottis come from different primordia; the left and right lymphatic drainage is not connected to each other, and the supraglottis, glottis and subglottis lymphatic drainage are independent, which provides a basis for surgical treatment of the larynx, especially partial resection. Different surgical procedures can be used according to the different locations of the cancer.

(1) Laryngeal carcinoma in situ or mild invasive lesions are suitable for laryngeal laser surgery and plasma surgery. They have the advantages of minimally invasive, less bleeding, low tumor spread rate, and good preservation of voice function. They are mainly suitable for early stage cases.

(2) Partial laryngectomy includes laryngeal dehiscence and vocal cord resection; frontal partial laryngectomy; vertical hemilaryngectomy; and some corresponding modified procedures are selected according to the extent of glottic cancer invasion.

(3) Supraglottic laryngectomy is suitable for supraglottic cancer.

(4) Total laryngectomy is suitable for advanced laryngeal cancer.

If laryngeal cancer can be controlled in the early stages of the disease, the cure rate of the disease can be greatly improved. Therefore, it is necessary to grasp some characteristics and laws of the disease in time. Only by deeply grasping these characteristics can it be beneficial to patients. It is best for patients to fully grasp these characteristics.
